int mbedtls_entropy_add_source(mbedtls_entropy_context*ctx, mbedtls_entropy_f_source_ptrf_source, void *p_source, size_tthreshold, intstrong ) Adds an entropy source to poll (Thread-safe if MBEDTLS_THREADING_C is enabled) Parameters:

Well. Yes. This function pretty much organizes entropy, but it is not the entropy source. It gathers entropy from all the sources in your platform, and conditions them into a single entropy. On your platform, you should check what is configured in regards of entropy source, and what functio...

mbedtls_err_ctr_drbg_entropy_source_failed 是一个错误码,表示在使用 Mbed TLS 库中的 CTR_DRBG(Counter-based Deterministic Random Byte Generator)随机数生成器时,熵源(entropy source)调用失败。熵源是用于为随机数生成器提供随机性(或“不确定性”)的数据源。
